Condenser and radiator air outlets

Abstract

A refrigerated mobile trailer is provided that includes a trailer body having an opening present in both its front wall and roof for receiving a transportable refrigeration unit. The refrigeration unit includes a housing having a roof panel and a side panel, a condenser assembly disposed within the housing that includes a condenser coil, an air inlet located in the side panel of the unit housing for receiving ambient air for circulation over the condenser coil and at least one air outlet for discharging circulated air to remove waste heat from the coil. The condenser coil is located adjacent to the roof panel of the refrigeration unit, and all air outlets for removing waste heat from the coil are advantageously located in the unit roof panel directly above the coil. The fact that all of the waste heat air outlets are located in the roof panel advantageously prevents air discharged from these outlets from recirculating back into the condenser air inlet when the mobile trailer is in a stationary position. Such a component arrangement also provides more useable space within the unit housing, which may be used to reduce the unit extension beyond the trailer front wall by 17%.

We claim: 
     
       1. A refrigerated mobile trailer, comprising: a trailer body having a floor, a roof, and a front wall, the front wall having an opening for receiving a refrigeration unit;   a transportable refrigeration unit mounted over said front wall opening the transportable refrigeration unit including a housing having an upper portion, a roof panel and a side panel, wherein said trailer body roof includes a recess contiguous with said front wall opening for receiving the upper portion of said housing, and a condenser assembly disposed within said housing including a condenser coil, an air inlet for receiving ambient air for circulation over said coil, and at least one air outlet for discharging circulated air away from said coil,   wherein all said air outlets are mounted on said roof panel of said housing for preventing air discharged from any of said air outlets from entering said air inlet.   
     
     
       2. The refrigerated mobile trailer as claimed in claim 1, wherein said recess receives a portion of said roof panel of said unit housing such that said trailer body roof and housing roof panel are integrated. 
     
     
       3. The refrigerated mobile trailer as claimed in claim 1, wherein said unit housing includes a side panel, and said air inlet is mounted on said side panel. 
     
     
       4. The refrigerated mobile trailer as claimed in claim 1, wherein said condenser coil is located adjacent to said air outlet. 
     
     
       5. The refrigerated mobile trailer as claimed in claim 4, wherein said transportable refrigeration unit includes an internal combustion engine having a radiator, and said internal combustion engine radiator is located adjacent to said air outlet. 
     
     
       6. The refrigerated mobile trailer as claimed in claim 4, wherein said condenser assembly further includes a blower for circulating air from said air inlet to said air outlet. 
     
     
       7. The refrigerated mobile trailer as claimed in claim 4, wherein said condenser coil includes first and second coil sections, said condenser assembly including first and second air outlets mounted on said roof panel adjacent to said first and second coil sections. 
     
     
       8. The refrigerated mobile trailer as claimed in claim 4, wherein the side of said condenser coil having the largest area is disposed over said air outlet to maximize air flow through said condenser coil. 
     
     
       9. The refrigerated mobile trailer as claimed in claim 6, wherein said blower includes a single width, backward inclined impeller. 
     
     
       10. A refrigerated mobile trailer, comprising: a trailer body having a floor, a front wall with an opening extending down from a top edge thereof, and a roof having a recess contiguous with said opening of said front wall;   a transportable refrigeration unit mounted over said front wall opening and in said trailer roof recess, said unit including a housing having a roof panel and a side panel, and a condenser assembly disposed within said housing, said condenser assembly including a condenser coil, an air inlet for receiving ambient air for circulation over said coil, and at least one air outlet for discharging circulated air away from said coil, wherein said air inlet and all of said air outlets are mounted on said side and roof panels of said unit housing, respectively, for preventing air discharged from any of said air outlets from entering said air inlet when said trailer is stationary and for increasing the amount of useable space within the unit housing.   
     
     
       11. The refrigerated mobile trailer as claimed in claim 10, wherein said condenser coil is located adjacent to said air outlet, and wherein the side of said coil having the largest area is disposed over said air outlet to maximize air flow through said condenser coil. 
     
     
       12. The refrigerated mobile trailer as claimed in claim 11, wherein said transportable refrigeration unit includes an internal combustion engine having a radiator for turning a refrigerant compressor, and said internal combustion engine radiator is likewise located adjacent to said air outlet. 
     
     
       13. The refrigerated mobile trailer as claimed in claim 11, wherein said condenser coil includes first and second coil sections, and said condenser assembly includes first and second air outlets mounted on said roof panel adjacent to said first and second coil sections. 
     
     
       14. The refrigerated mobile trailer as claimed in claim 13, wherein said refrigeration unit further includes an evaporator blower centrally disposed within said housing, and said first and second air inlets are located on either side of said evaporator blower. 
     
     
       15. The refrigerated mobile trailer as claimed in claim 14, wherein the condenser assembly includes first and second blowers for circulating air over said first and second condenser coil sections. 
     
     
       16. A refrigerated mobile trailer, comprising: a trailer body having a floor, a front wall with an opening extending down from a top edge thereof, and a roof having a recess contiguous with said opening of said front wall;   a transportable refrigeration unit mounted over said front wall opening and in said trailer roof recess, said unit including a housing having a roof panel and a side panel, and a condenser assembly disposed within said housing, said condenser assembly including a condenser coil, an air inlet for receiving ambient air for circulation over said coil, and at least one air outlet for discharging circulated air away from said coil, an internal combustion engine for powering a refrigerant compressor, said engine having a radiator;   wherein said air inlet and all of said air outlets are mounted on said side and roof panels of said unit housing, respectively, for preventing air discharged from any of said air outlets from entering said air inlet when said trailer is stationary, and said condenser coil and radiator of said engine is mounted adjacent to said air outlet.
